최근 고정된 연산량을 가지므로 하드웨어 구현이 용이한 고정연산량 (fixed-complexity) lattice reduction (fcLR) 기법이 제안되었다. 또한 한 개의 레이어에는 모든 성상점을 시도하여 높은 오류성능을 달성하는 QR-LRL (QR분해-least reliable layer) 신호검출기법이 제안되었다. 본 논문에서는 이 두 가지 기법을 결합하여 연산량은 고정되고 오류성능은 더욱 우수한 신호검출기법을 제안한다. QR-LRL에서와 같이 가장 신뢰도가 낮은 레이어 LRL을 제외한 후 LR을 수행하게 되면 LR의 연산복잡도가 크게 감소함을 보인다. 결과적으로 연산복잡도와 오류성능 관점에서 모두 제안된 방식이 기존 fcLR 기반 신호검출기법보다 우수한 성능을 달성한다. 모의실험을 통해 제안된 기법이 기존 기법에 비해 고정연산량 및 오류성능 관점에서 동시에 우수함을 보인다.

고려인삼의 적변내성 지표성분을 선발하기 위하여 적변지수가 낮아 적변에 강한 건전계통(LRL) 7계통과 적변지수가 높아 적변에 약한 적변계통(HRL) 7계통을 선발하여 시료로 사용하였다. 4년생과 6년생의 적변지수 상관관계는 고도의 유의성을 나타내었다. phenolic compounds 함량이 중심주 및 지세근 조직에서는 차이가 없었다. 피층조직에서는 적변인삼은 건전인삼보다 phenolic compounds 성분 함량이 높았으나, 적변의 정도를 동일하게 한적변계통군와 건전계통군간에는 phenolic compounds 함량의차이가 없어서 지표성분으로 활용 가능성이 없었다. 표피조직에서 적변삼은 건전삼에 비해 phenolic compounds 함량이 높았고, 적변삼이나 건전삼을 시료로 사용 했을 때 모두 적변계통군(HRL)은 건전계통군(LRL)보다 phenolic compounds 함량이 높아서, 적변삼 선발 지표성분으로 활용 가능성이 제시되었다.

Purpose: This study was aimed to evaluate the effect of blending oils on atopic dermatitis (AD) model of NC/Nga mice. Methods: Adult NC/Nga mice were assigned to 1 of 3 groups: control group (C, n=8), experimental group [AD-induced group, blending oil-treated group (E=8, 8)]. Mice in the E group were given a treatment of blending oils such as Lavender, Rosemary and Lemon Balm (LRL) for 2 sessions (every day) for 6 days. Results: The AD-induced mice with LRL blending oils treatment showed a significant decrease in epidermal thickness, number of mast cells and degranulation, expression of TNF-${\alpha}$ and scoring of sensual assessment. Conclusion: LRL blending oils may be a putative resource for the cure of or treatment of AD by the diminution of AD-pathological factors such as the epidermal thickness, the number of mast cells and degranulation as well as the expression of TNF-${\alpha}$.

The purpose of this paper is to develop and show the efficiency of the URL(Unload Request Logic) and LRL(Load Request Logic) of the dispatcher in the Fab(Fabrication) Manufacturing Execution System. These logics are the core procedures which control the material(wafer and glass substrate) flow efficiently in the semiconductor and LCD fab considering inter-bay as well as intra-bay material flow. We use the present and future status information of the system by look-ahead and the information about the future transportation schedule of Automated Guided Vehicles. The simulation results show that the URL and LRL presented in this paper reduce the average lead time, average and maximum WIP level, and the average available AGV waiting time.

고려인삼의 적변내성 계통을 선발하기 위하여 39계통을 포장시험에 공시하여 적변지수가 낮아 적변에 강한 건전계통(LR) 7계통과 적변지수가 높아 적변에 약한 적변계통(HRL)7계통을 선발하였다. 적변내성 인삼 선발을 위한 지표성분으로 무기성분의 가능성을 검토하기 위하여 I(건전계통군의 건전삼과 적변계통군의적변삼 비교), II(건전계통군의 건전삼과 적변삼 비교), III(적변계통군의 건전삼과 적변삼비교), IV(적변삼의 건전계통군과 적변계통군 비교), V(건전삼의 건전계통군과 적변계통군 비교) 5개 조합으로 구성하여 부위별로 무기성분 함량을 비교하였다. 계통군 및 적변지수별 무기성분 함량이 중심주 및 피층조직에서는 유의성이 없었으며, 지세근 조직에서도 일정한 경향이 없었다. 각 계통군내 비교에서 적변인삼은 건전인삼보다 표피조직에서 Fe, Na및 Al함량이 높았다. 표피조직에서 적변계통군(HRL)은 건전계통군(LRL)보다 적변삼이나 건전삼 시료 모두에서 Fe, Al함량이 높아 적변내성 계통 선발 지표성분으로 활용 가능성을 제시한다.

A semiconductor production system has sophisticated manufacturing operations and needs high capital investment for its expensive equipment, which warrants efficient real-time flow control for wafers. In the bay, we consider material handling equipment that can handle multiple carriers of wafers. The dispatching logic first determines the transportation time of each carrier to its destination by each unit of transportation equipment and uses this information to determine the destination machine and target carrier. When there is no available buffer space at the machine tool, the logic allows carriers to stay at the buffer of a machine tool and determine the delay time, which is used to determine the destination of carriers in URL. A simulation study shows this dispatching logic performs better than the procedure currently in use to reduce the mean flow time and average WIP of wafers and increase efficiency of material handling equipment.

Dubins showed that any shortest path of a car-like robot consists of exactly three path segment which are either arcs of circles of radius r(denoted C), or straight line segments(denoted S). Possible six types classified into two families, i.e. CSC and CCC. CSC includes 2 types(LRL and RLR) and CSC includes 4 types(LSL, RSR, LSR, RSL). This paper proposes new formulae for CSC family to find the shortest smooth path between the initial and final configurations of a car-like robot. The formulae is used for finding connection points explicitly between C\longrightarrowS and S\longrightarrowC which are necessary for real applications. The formulae have simple forms mainly because they are transformed into origin of their original coordinates of initial and target configuration, and derived from a standard forms which are a representative configuration of LSL and LSR type respectively. The proposed formulae, which are derived from the standard forms, are simple and new method.

This study was a succession of the paper of Reference 1), and was an attempt to quantify the Level of Need of Living through the relation bet ween Ds(Degree of Sufficietncy) and Di(Degree of Importance). The relation formula was: Level of Need of Living=Di×(5-Ds)＋Di×lrl. From the caculated values, some indicators of highest and lowest Level of Need of Living could be cleared and by them the Level of Consumers' Life and Conciousness could be presumed. The main results are as follows. 1. The Level of Need of Living that the indicators of the equity of income allocations, social mobility, judicial equality, and residential amenity showed was the highest, and that of the life of planned expenditure, the development of transportation, the longevity, an the high level of education was the lowest. 2. The rural residents showed the highest Level of Need on the indicators of medical care, culture and basic living expenditures. 3. The higher the perception of social class and the satisfaction of living was, the lower the Level of Need Living was. 4. In general, it was presumed that the Level of Consumer's Life was in the term of sufficiency of the second need, which durable electric consume products were purchased under the intended conciousness of consumers to be as like as others.
